Database InfoSec: Firewall (W7)

I often feel that organizations think they won’t ever be hacked, but have they ever stopped to think about the many reasons other companies are being attacked?

According to DataSunrise, Inc (2017), three reasons why your databases can be hacked is:
1. Your competitors want to get a piece of your business.
2. Bad guys are planning to steal your data to sell it on the black market or blackmail you.
3. There are some hackers that breach the databases just for fun.

Firewall

firewallTo protect your database against hackers, there are many security tools, but the easiest is a firewall. “Database Firewalls are a type of Web Application Firewalls that monitor databases to identify and protect against database specific attacks that mostly seek to access sensitive information stored in the databases.  Database Firewalls also enable to monitor and audit all access to databases through the logs maintained by them” (K, 2011).

But how do firewalls defend your databases?

The firewall has a set of security audits based on past attacks, called signatures. “These “signatures” resemble any SQL statement sequences known as typically used by hackers. The firewall intercepts incoming SQL query and compares its code with known signatures” (DataSunrise, Inc, 2017). Because the signatures are based on past incidents, the list is continually being updated, so firewalls can always defend your database, in case it’s hit with one of the latest known threats.

I recommend that all database systems consist of a firewall. I believe they’re easy to install and maintain. However, if you don’t quite feel the same, there’s several software programs that’ll install and provide updates for your firewall, like Oracle.
